To all whom t may concern.'

Be it known that I, ISAAC It.

Fig. 2 is a perspective view of the auxiliary shoe removed from the permanent shoe. Fig.3 is a perspective view ofthe permanent shoe. Figst, 5, and 6 are calks. Figs. 9, 10, 11, and 12 are bolts.

Fig. 1: A is the shoe, as seen completed and applied to the hoof. B B B are the calks. C' C C C are the screw-bolts which secure the auxiliary shoe to the permanent shoe. d d are steady-pins, which guide and secure the auxiliary shoe in position on the permanent shoe. x' w .00' are moldings.

Fig. 2: Azis the auxiliary shoe, with the calks, steady-pins, and screw-bolts removed. The apertures a2 a2 a2 are swaged tapering, with a molding around them. g2 q2 are holes for the steady-pins. h2 h2 h2 h2 are holes which admit the bolts O O C' C. (Shown in Fig. l.)

Figs. 9,10, 11, and l2 are screW-bolts,whch are used in securing the auxiliary shoe to the permanent shoe.

The permanent shoe being constructed as set forth and shown in Fig. 3, and secured to the hoot in the usual and well-known manner, the auxiliary shoe also being constructed as set forth in Fig. 2, with apertures alzctzamade tapering, and calks, Figs. 4, 5, and 6, made Wedge-shaped, as shown by Figs. 7 and 8, to lit the apertures, and affixed in them, the auxiliary shoe being adjusted to the permanent shoe, so that the steady-pins d3 d3 (shown in Fig. 3) are inserted in the holes g2 g2, Fig. 2, the bolts 9, 10, l1, and l2 being firmly set in, as shown in Fig. l, the calls are firmly held in the apertures and in position, braced by the moldings x x x. (See Fig. l.)

I do not claim the auxiliary shoe or the manner set forth for securing it to the permanent shoe; neither do I claim movable calks, or any device previously invented or patented for securing calks to metallic shoes; but

What I claim as my invention, and desire to secure by Letters Paten t, is-
